Which principle specifically instructs not to destroy more than the mission requires

• A. First Principle
• B. Ninth Principle
• C. Sixth Principle
• D. Eighth Principle

Answer: (C)

Economy of force is the principle that guides using the minimum amount of force necessary to achieve the objective, concentrating power where it matters and avoiding unnecessary destruction. This means selecting tactics and resources that accomplish the mission without overkill, preserving assets for the next steps and minimizing collateral damage. So, the statement about not destroying more than the mission requires directly reflects economy of force, making the Sixth Principle the best answer. The other principles cover different aspects of warfare—such as command, security, or decisive action—but they don’t specifically instruct restraint in destruction.
